A particle of mass `m` moving eastward with a velocity `V` collides with another particle of same mass moving northwards with the same speed `V`. The two particles coalesce and the new particle moves in NE direction. Calculate magnitude and direction of velocity of new particle.

A

`sqrt2v`

B

`v/sqrt2`

C

`v/2`

D

`2 v`

Text Solution

Verified by Experts

The correct Answer is:
`(2)`

Resultant momentum, `2mv. = sqrt((mv)^(2) + (mv)^(2)) = mv sqrt 2
v. = v/sqrt2`
